Embodiment Construction
[0030] By adopting the technical scheme of the embodiment of the present invention, it is possible to effectively avoid the problem of reducing the loading efficiency of ACL rules in the ACL rule loading process in the prior art due to a large number of redundant relocation operations.
[0031] The embodiment of the present invention provides a method for loading ACL rules, which is applicable to various devices applying the ACL function, such as routers and switches. The preferred implementation modes of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] refer to image 3 As shown, the specific processing flow of an ACL rule loading method provided by the embodiment of the present invention includes:
[0033] Step 301: Receive a data loading request, where the data loading request includes the number of ACL rules to be loaded.
[0034] Specifically, the data loading request may be sent by other devices connected to t...

The invention discloses an ACL rule loading method and device, and aims at solving the problem of relatively low loading efficiency caused by a large amount of redundant moving operations in the ACL rule loading process in the prior art. The method comprises the following steps: receiving a data loading request which comprises the number of ACL rules to be loaded, and determining a loadable range in a storage medium which is used for storing the ACL rules; and when the number of basic storage units in the loadable range is less than the number of the ACL rules to be loaded, moving the ACL rules stored in the storage medium, taking the idle basic storage units obtained through the moving as expandable basic storage units and adding to the loadable range until the number of the basic storage units in the loadable range in which the expandable basic storage units are added is greater than or equal to the number of the ACL rules to be loaded, and loading to the ACL rules to be loaded into the loadable range in the storage medium in sequence.
Description
technical field [0001] The invention relates to the communication field, in particular to a method and device for loading ACL rules. Background technique [0002] The access control list (English: Access Control List, abbreviation: ACL) is a list of instructions on the interface of routers and switches, and is used to control the data packets entering and leaving the ports. ACL is composed of several ACL rules. Due to the powerful and flexible ACL function, and storing the ACL rules in the ACL through the ternary content addressable memory (English: Ternary Content Addressable Memory, abbreviation: TCAM) can ensure the efficiency of finding ACL rules, more and more business Start using ACLs. In more typical "policy routing" applications, such as redirecting packets of a specific Internet Protocol (English: Internet Protocol, abbreviation: IP) to a certain next hop, transparently interconnecting multiple links (English: Transparent Interconnection of Lots of Links, abbrevia...
